Manx
Shearwater is a regular visitor in small numbers, especially in July.
It thus occurs somewhat earlier than Sooty Shearwater. I have recorded
this species on the majority of visits during the first half of July -
a time when Skogsøy is very infrequently visited. Strong
onshore winds at this time of year are not required to bring this
species within range - Manx are recorded just as often during other
wind directions. Later in the season, and for larger numbers, a brisk
westerly will be sure to increase the chances of connecting with this
species.

The blue line shows number of visits, the orange one the number of
visits when Manx have been recorded and the green one shows the
total involved.
